Install requirements.txt uses a different path

Question

Fellow users,

I am trying to install a requirements.txt file (via cmd prompt: "pip install -r "path\to\file"). The problem is that my system returns an OSError with a totally different path than I entered. What can I do to prevent this?

*I already enabled a path length above 260 characters.

The console feedback:

C:\Users\schum\BT CODE>pip install -r "C:\Users\schum\BT CODE\requirements.txt"
